Outward migration of Gnathostoma spinigerum in interferon alpha treated hepatitis C patient.

After the first dose injection of pegylated interferon alpha-2b (Peg-IFN alpha-2b) to a HCV infected Thai woman, she developed cyclic painful swelling nodules on right upper quadrant of abdomen and right anterior lower chest wall. The nodules subsided spontaneously within 1-2 days but were recurrent after every Peg-IFN alpha-2b injection. She also experienced acute urticaria. After nine months of therapy, an immature male of G. spinigerum migrated out from the skin nodule shortly after a Peg-IFN alpha-2b injection as scheduled. The worm showed a head-bulb bearing 8 transverse rows of spines which indicated immature stage. It had well defined four pairs of caudal papillae on posterior body part which were used to identify male gender. Painful migratory swelling and urticaria disappeared after the parasite was removed. She was continually treated and had sustained both virological and biochemical responses to HCV treatment. This case demonstrates that the outward migration of G. spinigerum may be stimulated by the injection of Peg-IFN alpha-2b.

Tuberculous pyomyositis.

Tuberculosis, caused by Mycobacterium tuberculosis is a common infection both in immunocompromised and normal hosts. Its clinical manifestation can by divided as pulmonary and extrapulmonary form. Pyomyositis caused by M. tuberculosis is extremely rare. The authors report 2 patients, one with underlying dermatomyositis, and the other with polymyositis. The diagnosis was delayed according to nonspecific symptoms and masking effect of steroid therapy, which led to complications. Microscopy and culture of the pus confirmed the diagnosis. Surgical drainage was done and antituberculous therapy was given. The patient with dermatomyositis was complicated by drug induced hepatitis and died but the other was cured. Tuberculous pyomyositis should be considered in patients who are immunocompromised hosts.

Exertional rhabdomyolysis following excessive exercise of university freshman cheer-training.

Exertional rhabdomyolysis is a life threatening condition resulting from lysis of muscle cells after vigorous exercise. It can cause many complications such as renal failure. It occurs most commonly in military personnel but also in civilians who have excessive excercise after work. Two cases of freshmen who had exertional rhabdomyolysis were reported to illustrate the potential risk of cheer-training. Appropriate measures should be arranged to prevent this condition. Diagnosis and treatment should be given promptly to prevent serious complications.

Quinolones and Salmonella septic arthritis.

Salmonella septic arthritis is an infrequent infectious disease but can cause progressive joint destruction resulting in disability. The authors retrospectively reviewed cases with culture proved Salmonella septic arthritis in Srinagarind Hospital, Khon Kaen from 1994 to 2000. There were 23 episodes in 16 cases; all had underlying diseases and a history of steroid abuse or steroid and immunosuppressive therapy. Systemic lupus erythematosus was the most commonly found underlying disease (56%). Salmonella group D and group B were isolated in 13 and 3 cases. Most first episodes had acute onset of monoarthritis. The antibiotics used as initial treatment of the first episodes were beta lactam, cotrimoxazole or quinolones. There were 8 cases with disabled sequelae and 7 cases with relapse. For 13 evaluable first episodes, relapse occurred in 3 cases in the cephalosporin/penicillin and 4 cases in the cotrimoxazole treated group but none in the quinolones. Six relapse cases were treated successfully with quinolones as well as one with cotrimoxazole. Although 5 relapse cases treated with quinolones had previous progressive joint destruction or avascular necrosis, there was no further joint damage after re-treatment with quinolones. In conclusion, quinolones were more effective than beta-lactams and cotrimoxazole for the treatment of Salmonella septic arthritis to prevent relapse and progressive joint destruction.
